I know there is probably a thread somewhere addressing aluminum and steel rounds, but thought I'd just ask anyway.

I've seen boxes of Federal aluminum case 9mm at Walmart for about $9/box, and thought before buying any, I'd see if it is considered ok to shoot in a Sub 2000 (or anything else, for that matter).

Thoughts?

The manual says no, that being said Ive shot both in my personal sub2000. Cant say it's going to be safe in yours though. The federal aluminum cased ammo is the most inaccurate ammo ive shot through mine, very bottom of the bucket stuff.

Thanks for the input. I think I'll avoid it.

Aluminum cased ammo really shouldn't be used in any blowback action...be it a Sub2000 or a pistol. It's OK for locked breach actioned weapons.

The problem is a blowback actioned weapon starts moving so quick it can allow case separation or actual blown apart cases when using aluminum cased ammo.


*EDITED*

PS...aluminum shouldn't be used in a firearm that doesn't support the case fully, either.
Such as Glocks. They tend to blow up...YMMV.

Just tossing that out there for fun? Providing some evidence of such would be nice. :)

For the record, I "liked" haugrdr's post (#4) before that last part was added, and never would have liked it with that last part.

You asked...would you like more? Do a search on Google, hundreds pop up...it's not safe in a blowback firearm.

Rick, that part I agree with. Blowing up Glocks, um no. You cited posts about not using it in blowbacks, which is true.

So, I am still waiting for some evidence of aluminum cased ammo blowing up a Glock, which is what I asked you to provide.

Mark, I'm not gonna do a search to prove what I posted. It's general knowledge that aluminum cased ammo could blow out or cause problems when fired thru a semi auto that doesn't support the cases fully. Forget I posted "Glock" and pretend I posted the generic "semi auto with unsupported cases."

And instead of "blow up" pretend I posted "the case could blow out." Which is what I meant in the first place.

It's my opinion (and others ) that you shouldn't use aluminum cased ammo in a semi auto blow back firearm that doesn't support the cases fully. My honest and as far as I know truthful opinion.

With all due respect Rick, what you asserted...

PS...aluminum shouldn't be used in a firearm that doesn't support the case fully, either. Such as Glocks. They tend to blow up...YMMV.
Is NOT provable, whether you search for it or not. You made a false accusation and I called you on it. Now you want me to "pretend" you said something you did not and make inferences based on what you assert is general knowledge that something "could" happen?

Glocks are NOT blow back firearms, the Sub2000 is. A case rupture with a factory round with an aluminum case is no more likely to occur in a Glock than with a factory round loaded in a brass case.

To be clear...Aluminum, brass and steel cased ammo has NO safety differential in a Glock at all. Aluminum and steel cased ammo does have a safety differential to brass cased ammo in the Sub2000.

"Calling" a forum mod, much less calling him a liar is not a good way to ensure your longevity as a forum member. I don't care whether you use all due respect or not.

Are ALL Glocks dangerous? No. Can ANY gun have a KB? Yes. Very likely due to the sheer numbers of Glocks being used in competition they seem to be reported in more cases. And the problem is with the larger calibers (357SIG, 40S&W, 45ACP, 10mm), BUT IT DOES EXIST.

I understand you own 2 gun related companies. I understand you claim to have a VAST amount of gun knowledge. In your own words, NOT provable. I don't claim either. I have a good general firearm base of knowledge, and I read a lot. You've been a member here for less than a week. How about you try to get a feel for how this forum operates before you decide to take it over with all of your superior knowledge. Nuff said?

Now let's get this back on the topic of whether 9mm or .40S&W aluminum cased ammo is a good choice for the Sub2K. The answer is no due to the blowback action.

Mod or member, new or old, does not give anyone a right to say things that are inaccurate or misleading. If Rick had not made a false assertion, there would have been no issue, period.

I get handed what I write in court and depositions, so it must be accurate no matter where I write it.

Also, the link you posted is about Glock KBs with all kinds of things, NOT aluminum cased factory ammo.

If you wish to threaten my forum longevity due to stating facts, feel free, and prove those who told me you would right.

If you do a little research regarding your links, instead of using them to try and support an untenable position related to Glocks and aluminum cased ammo, you might find that I was the first person to publically talk about the issue of Glock KBs. I have examined over 200 blown Glocks and there are a myriad of issues, but it is not aluminum cases in the Glock chambers.

Rick was referencing unsupported chambers in Glocks. A known issue especially in the larger calibers, which I pointed out. I have NO issues with shooting Glocks and no personal dislike for them beyond the fact that I can't get comfortable with their grip angle.

I don't care what kind of casing material was involved. Your argument is specifically against his statement about Glocks. You agreed with his statement that aluminum cased ammo is not good in a blowback action like the Sub2K. Your beef was about his statement on Glocks. I provided both an article and photo evidence (links) showing the lack of full chamber support in their barrels. You wanted evidence, I searched and provided it. Yes I read your Dillon link and that went even further into posing that lead bullets might be the problem from what I could glean.

I'm not going to continue this argument. It has moved away from the topic and into Other Guns (Glocks). If you want to continue it open a thread in the Other Guns sub-forum and cast aspersions on our honesty in there.

I have to apologize here...I did make a mistake when I searched for this info. It's the Glock 42 that is a blowback (.380)...and thus aluminum ammo is not recommended to be used. That's right from Glock, I'm sure you know this.

Again, I can find way way too many sites on the internet that support my assertion that aluminum ammo shouldn't be used in a blowback firearm or in a firearm that doesn't support the case fully. I should have stuck to just posting about the Sub2000 that was asked about...in the future I shall.

Mark, I was asked to be a Mod on the forum for a couple of reasons...I interacted well with the forum in general, I have a good general knowledge of KelTecs (and firearms in general), I have pretty darned good Google-Fu and know how to use it...and I think one reason is I have a good humor. I also have a pretty good way of putting words to paper...most of the time. I can mess that up in a quick hurry also...lol.

I'm a volunteer...the mods don't get paid, we do it because we like doing it. We love dealing with people that also have a love for the forum, we put up with others that don't have that connection like we do. We don't do well at all with people that are just here to bitch and gripe and cause us troubles. We tend to rally around each other in support when one of us is called out, be it rightly or not...we are defencive of each other. We are a very good team.

Another reason I think I was asked to be a Mod is I'm not shy about using my Mod superpowers when I feel they're needed...in support of the Forum or the Rules or the other Mods. Such as this case in dealing with you. You don't like my answer...or my lack of support for my answer. Well, tough tooties. I gave my opinion and what I could find on the internet as my trying to be helpful answer...which is still my opinion. Either prove me wrong and shut up, or move on to another topic and shut up...or leave. Either voluntarily or I'll do it for you. You're more than welcome to stay, but knock off the attitude. Try to be helpful, and grow to be a member of a very good forum...but knock it off, one way or another.

I have shot thousands of the Federal aluminium 9mm rounds purchased at Walmart, but they DO NOT cycle well at all in my Sub 2000. About a third of the time they short cycle and the empty case is not ejected. They work fine in my other guns.
